Hydraulic Relief Valve
DB/DBW is pilot-operated pressure relief valve, with both the pilot valve and the main valve adopts poppet structure. Relief valve DB/DBM is capable of controlling the system pressure, and particularly, DBM is designed to unload the pressure at any time.
Pressure relief valve DB/DBM employs casted inner flow channel, which allows for large flow capacity. It is distinguished for simple structure, little noise, and stable performance.
DB series is mainly applied in relief valve,safety valve, and remote control relief valve, and DBM is designed for unloading the system pressure and multi-level pressure control. Both the two types are extensively applied in aerospace, equipment engineering, mining, and chemical manufacturing industries.

How to Choose the Right Specification
You can determine the model you need according to the tables below. Please feel free to contact us if you have any questions.
DB (W) 30B Pressure Relief Valve
The characteristic curves were measured with external, at zero pressure, pilot oil drain.
With internal pilot oil drain the inlet pressure increases by the outlet pressure present at port B.
DB (W) 50B
Characteristic curves (measured at v = 41 mm2/s and t = 50℃)
The characteristic curves were measured with external, at zero pressure, drain pilot oil.
With internal pilot oil drain the inlet pressure increases by the outlet pressure present at port B.
